Answer:
1. They have to be able to reproduce, either asexually or sexually.
2. They have to be able to respond to stimuli.
3. They have to have cells, either as a unicellular organism or as a multicellular organism.
4. They have to grow and develop.
5. They have to have homeostasis. This means that they can maintain their own body temperature. Think of this as a thermometer for the body.
6. The last thing is that all living things also have to be able to do is move.
Explanation:
Answer:
b. methylation.
Explanation:
Science can be defined as a branch of intellectual and practical study which systematically observe a body of fact in relation to the structure and behavior of non-living and living organisms (animals, plants and humans) in the natural world through experiments.
Genome editing can be defined as a high-tech process which avail scientists the opportunity or ability to remove (delete), replace and insert Deoxyribonucleic Acid (DNA) sequence in a living organism such as bacterias, animals, plants etc in order to correct a genetic disorder and to improve on their physical and chemical conditions.
Transcription can be defined as a process which typically involves re-writing the informations contained within a Deoxyribonucleic Acid (DNA) into a Ribonucleic Acid (RNA) by enzyme RNA polymerase.
Hence, DNA regions that are transcriptionally silenced by hypercondensation have often undergone a modification of their cytosine residues termed methylation.
For example, CpG island methylation transcriptionally silences about 650 to 800 genes in patients suffering from colorectal cancer.
Anaphylaxis is a severe, potentially life-threatening allergic reaction. It can occur within seconds or minutes of exposure to something you're allergic to, such as peanuts or bee stings.
Answer:
(B) calmodulin
Explanation:
Calcium in cells acts as second messenger molecule which regulates the very important physiological and cellular process of cell-like neurotransmission, cell migration, secretion, fertilization and many others.
Calcium acts as a messenger by binding to a calcium-binding protein called calmodulin. Calmodulin forms complex with 4 calcium ions through the side amino acids present in the structure of calmodulin.
Thus, calmodulin is the correct answer.
The solution to the above question using the formula f=1/T where. T=0.5seconds is f=1/0.5= 2 hertz
